A vulnerability has been found in Vnet/IP Interface Package provided by Yokogawa Electric Corporation. If affected product receives maliciously crafted packets, Vnet/IP software stack process may be terminated. The affected products and versions are as follows: Vnet/IP Interface Package (for CENTUM VP R6 VP6C3300, CENTUM VP R7 VP7C3300) R1.07.00 or earlier
The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.
While assertion is good for catching logic errors and reducing the chances of reaching more serious vulnerability conditions, it can still lead to a denial of service. For example, if a server handles multiple simultaneous connections, and an assert() occurs in one single connection that causes all other connections to be dropped, this is a reachable assertion that leads to a denial of service.
